Disable Dnssec Bind
and rise to the top BIND server has tons of “no valid RRSIG” errors up vote 1 down vote favorite I have a forward-only BIND9 server running on the LAN and it logs hundreds of errors per day like: Aug 29 18:38:29 nuc named[850]: error (no valid RRSIG) resolving 'ubuntu.com/DS/IN': 75.75.75.75#53 Aug 29 18:38:31 nuc named[850]: validating @0x7fc6d826ed50: com SOA: got insecure response; parent indicates it should be dnssec-validation auto secure Aug 29 18:38:31 nuc named[850]: error (no valid RRSIG) resolving 'medium.com/DS/IN': 75.75.75.75#53 Aug 29 18:38:31 nuc named[850]: validating @0x7fc6d4014b80: com SOA: got insecure response; parent indicates it should be secure It appears clients are still getting results, but these messages are filling up the logs. Relevant lines in named.conf: forwarders { # Comcast 2001:558:feed::1; 2001:558:feed::2; 75.75.75.75; 75.75.76.76; }; forward only; dnssec-enable yes; dnssec-validation auto; dnssec-lookaside auto; What do these errors really mean is happening? Is this a misconfiguration on my end or Comcast's? domain-name-system bind dnssec share|improve this question edited Aug 30 '15 at 5:32 chicks 2,16131228 asked Aug 30 '15 at 2:51 jmw 813 add a comment| 1 Answer 1 active oldest votes up vote 2 down vote accepted It looks like Comcast's servers are deliberately stripping out DNSSEC signatures from the responses they're giving you, so your server cannot validate com. (in this case) even though it knows that one should be signed. This is unlikely to cause any directly noticeable problems, it just leaves you and your users wide open for all the attacks that DNSSEC was created to protect against. Exactly why Comcast want to reduce your level of security you will have to ask them. share|improve

So, now I have no DNS resolution over my VPN tunnels anymore. Version-Release number of selected component (if applicable): bind-9.7.3-1.fc13.i686 bind-chroot-9.7.3-1.fc13.i686 bind-libs-9.7.3-1.fc13.i686 bind-utils-9.7.3-1.fc13.i686 How reproducible: Always Steps to Reproduce: 1. Configure forwarder(s) for forward and reverse DNS resolution 2. Do forward and reverse lookups from both end of the tunnels 3. Observe results Actual results: Hostname or IP lookup yields: not found: 3(NXDOMAIN) And in syslog: got insecure response; parent indicates it should be secure Expected results: Normal DNS resolution like it used to be. Additional info: Comment 1 Eddie Lania 2011-03-06 13:16:12 EST I think I see the problem because I have lines in the named log file like: 06-Mar-2011 18:52:45.886 lame-servers: info: error (no valid RRSIG) resolving 'p3000fedora.lania-intra.net/DS/IN': 192.168.169.4#53 06-Mar-2011 18:52:45.902 lame-servers: info: error (insecurity proof failed) resolving 'p3000fedora.lania-intra.net/A/IN': 192.168.169.4#53 06-Mar-2011 18:55:43.981 lame-servers: info: error (no valid RRSIG) resolving 'hestia.lania-intra.net/DS/IN': 192.168.169.4#53 06-Mar-2011 18:55:44.149 lame-ser
